Unexpected harvest

During the exam, I remember that in the third grade, I participated in the Guangbo Cup math competition.

Found a problem: 25 × 100 × 4 =? I think: This can be easily calculated, 25 × 4 = 100, 100 and multiplied by 100 is equal to 10000. Haha! This question is equal to 10,000! Sitting next to Wang Yifan secretly told me: "You can count!" I think: You tell me how to do it, I will not do it! Humph! So I continued to do the topic. But always worried, afraid to get the wrong question. Ugh!

On the day of the hairpin, I saw it, it was 100 points! I saw another row of red letters, which read: Very good! This question is very simple for you!

what! I don't have to use other people's methods, I can test a good result without the teacher's method! This is an unexpected harvest!
